This inventionrelates to improvements in atomizers for vacuum cleaners, and the object thereof is to provide in connection with a f vacuum cleaner of usual construction, a dej vice by which airr pressurederived from the".

. vacuum cleaner may be utilized to apply atomized liquid upon objects to'be treated therewith. The character'o the liquidfis Vimmaterial to the invention,but may bev such as Vliquid disinfectants, cleansing iuids, 1n-

seoticides or `coloring matter in liquid form.

This object is accomplished V bythe con struction illustrated in the accompanying drawings, in which Y Y Y Y' Fig. l is a plan view of. an atomizer in whichthe invention-is embodied; and Fig. 2 is a side* elevation projected from Fig. l, a portion being broken away.

The characters appearing in the descrip-- tion'refer to partsshown inthe drawings and designated thereon byk corresponding 3, its upper end projectingto point adj acent the outer end of the'noz'zle2, and its lower portion extends down through the lidvr into the vessel 5 to a point 'adjacent the bottom thereoL-andaregulating valve 8 is'provded for controlling the discharge of Vliquidfrom the .vessel throughf said tube, Upon the top of ythe tubular handle ismounted a bracket 9 in which is pivoteda lever 10 that is actuated in one direction by. aA spring 1l. The

forward end of saidl lever has adjustably mounted in connection therewith a stem-l2 vwith an elongated tapering'lower end, which end constitutes a valve 13 that'proje'cts into,

and normally`closes theupper end of the "0 discharge tube 7, and is "withdrawn from vfrom the tube l through the duct 6 ,andis also 'upper endof the discharge tube 7.` The pressure ofv air in thev vessel.` causes the liquid 20 4pass up through the tube krinto'the path, of the said tube by said lever ywhenthe thumbp'iece 14'o1r therearfend of the4 lever is depressed(` vThe atomizin'gt device-is'. connected with a vacuum cleaner 'of the usual A type (n'otv shcwn),' ther'e beinga'hose 16 into oneendfofj lili'y which is ypositio'ned'the extendingend ofthe 1 f Y tubularhandle l,. 'theother endfof thefhosev beingjconriected with the outlet ofv the tang. v l' chamber of fthevacu'um cleanengf Thepar-Tv Q ticular manner of attachment of the hose'to 60, y

the outlet isfimmaterialyas any suitablefary rangement Vhay be employed whereby the dis` charge ofair rom'the :tan chamber of the cleaner entersthe hose andisconveyed therebyto theitubular handle.

In the operation of Vtheinvention Vthe air ysupplied to the handle through? the hose under pressure fromfthe vacuum cleaner passes discharge'din a jet from the nozzle 2 pastjther in the ves'selfwhen the valve 13 is raised, to

air that is dischargedfrom the nozzle, so that 7 the liquid becomes atomized and carried by vthe force ofthe airjjet in a more or less defig vnite direction. Byfmanipulating the valve 1,*

y8 the rate ofdischarge of the liquid-through 's theftubemay be regulated, The atomizinggp devicemay be' carriedabout' by grasping thefobjectsfby depressing the thumb-'piece'lLto such'extentv as to allow the. escape of liquid from the tubeVK 7, the ratelof dischar e being more' or less according totheextent't e'valve i v13 is raised, whichrate is'also limited by adjustmentoi thevalve 8;"

, Vhat I claim .is:-

' 1. An' atomizer comprising a vessel `having a removableflid';` a ba'Sesuperimposed 1 upon said lid; a discharge tube Vdisposedfwithinsaid'vessel,itsupper end extending through i i and projecting above -said base;v` a ltubular member positioned on'said base and havinga.

i nozzle vdisposed at approximately right anglesto the upper end of thedischarge tube,

vthere being an'air duct extending through said v :f l lid and base into said tubular member; an ad` i justing valve `for regulating the flow through said discharge tube; an operating valve eX- tending into and normally closing the discharge end of said discharge tube, said valve independent of said adjusting Valve having operating means therefor; and a hose connection for supplying air under pressure to said tubular member.

2. An atomizing device comprising a Vessel for containing the material to be atomized; a liquid discharge tube extending from Within the lower part of the vessel through the top thereof and provided With a valve for regulating the flow of liquid therethrough; a tubular member having a nozzle positioned on said vessel with its nozzle spaced from and directed at approximately right angles across the upper end of said discharge tube, there being an air duct connecting said Vessel and tubular member; and an operating Valve extending into and normally closing the discharge end of said liquid discharge tube, disposed in front of the tip of said nozzle, and having an operating lever in connection therewith for its support and by Which it is actuated independently of the other valve.

In testimony whereof I ahix my signature.
